Studies on chemical constituents from the root of Polygonatum kingianum / 中国中药杂志

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the anti-HIV constituents from the root of Polygonatum kingianum.</p><p><b>METHOD</b>The compounds were isolated by column chromatography on silica gel, Sephadex LH-20, MCI-gel CHP-20P and their structures were determined on the basis of their spectroscopic evidence including IR, MS and NMR data.</p><p><b>RESULT</b>13 compounds were isolated, of which nine compounds were identified as liquiritigenin, isoliquiritigenin, 4', 7-dihydroxy-3'-methoxyisoflavone, (6aR, 11aR)-10-hydroxy-3, 9-dimethoxypterocarpan, 5-hydroxymethyl-2-furancarboxaldehyde, salicylic acid, n-butyl-beta-D-fructopyranoside, n-butyl-beta-D-fructofuranoside, n-butyl-alpha-D-fructofuranoside.</p><p><b>CONCLUSION</b>Compounds 1-6 were obtained from this plant for the first time.</p>
